Benefits of technology

The invention provides a monitor and a method for accessing the monitor's EDID (extended display identification) using RFID technology. This allows for better quality and reliability of EDID transmission, as well as reducing labor requirements and improving flexibility in reading and writing EDID. The monitor includes a memory and a RFID control unit that can send and receive EDID information. The method involves performing an EDID reading procedure and a writing procedure, allowing for easy access to the monitor's EDID. Overall, the invention provides a more efficient and reliable way to access and manage the monitor's EDID.

Problems solved by technology

However, due to instability of the VGA cable mentioned above, accessing EDID by the VGA cable fails very easily.
Furthermore, coupling VGA signal line to the monitor requires more labors, thereby reducing production and serving efficiency and increasing production cost.

Embodiment Construction

[0020] Referring to FIG. 3A, a structure diagram of a monitor according to a preferred embodiment of the invention is shown. The monitor 300 is used for a RFID reader 312 to read and write EDID therein. The monitor 300 includes a RFID controller 310, an antenna 311 and an EEPROM 320. The EEPROM 320 is for storing the EDID. The RFID controller 310 is coupled to the EEPORM 320 for transmitting the EDID from the EEPROM 320 to the RFID reader 312 via the antenna 311 and stores the EDID inputted from the RFID reader 312 to the EEPROM 320 via the antenna 311.

[0021] The antenna 311 is for receiving RFID-format signals outputted from the RFID reader 312, including a read data signal Sr and a write data signal Sw. The antenna 311 generates an induced current I for driving the RFID controller 310 as receiving the read data signal or write data signal Sr or Sw. The power pin Vcc of the RFID controller 310 is coupled to the power pin Vcc of the EEPROM 320. The driven RFID controller 310 output...

Abstract

A monitor includes a memory and a radio frequency identification (RFID) control unit. The memory is for storing extended display identification data (EDID). The RFID control unit, coupled to the memory, is for sending the EDID stored in the memory to the RFID reader and storing the EDID sent from the RFID reader into the memory. The EDID access method includes performing an EDID reading procedure including sending out a read data signal to the RFID control unit by using the RFID reader, and packing the EDID stored in the memory into a RFID-format signal and outputting the RFID-format signal to the RFID reader; and performing an EDID writing procedure including sending a write data signal having the EDID to the RFID control unit by using the RFID reader, and writing the EDID of the write data signal into the memory by using the RFID control unit.

Description

[0001] This application claims the benefit of Taiwan application Serial No. 94125468, filed Jul. 27, 2005, the subject matter of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates in general to a monitor and extended display identification data (EDID) access method thereof, and more particularly to a monitor in which EDID are accessed by using radio frequency identification (RFID) and EDID access method thereof. [0004] 2. Description of the Related Art [0005]FIG. 1 is a structure diagram of a conventional monitor. Referring to FIG. 1, the monitor 100 includes a video graphic array (VGA) connector 110 and an electrically erasable programmable read only memory (EEPROM) 120. The EEPROM 120 is a plug-in component for storing EDID. The VGA connector 110 is coupled to the EEPROM 120 via serial clock (SCL) and serial data (SDA) transmission lines of an inter-integrated circuit (I2C) bus 130. Besides, the powe...
